Sensing Strain-induced Symmetry Breaking by Reflectance Anisotropy Spectroscopy
M. Volpi, S. Beck, A. Hampel +3
Intentional breaking of the lattice symmetry in solids is a key concept to alter the properties of materials by modifying their electronic band structure. However, the correlation…
Interplay between breathing-mode distortions and magnetic order in rare-earth nickelates from magnetic models
Danis I. Badrtdinov, Alexander Hampel, Cyrus E. Dreyer
We use density-functional theory calculations to explore the magnetic properties of perovskite rare-earth nickelates, NiO, by constructing microscopic magnetic mod…
First-principles study of the electronic, magnetic, and crystal structure of perovskite molybdates
Jeremy Lee-Hand, Alexander Hampel, Cyrus E. Dreyer
The molybdate oxides SrMoO, PbMoO, and LaMoO are a class of metallic perovskites that exhibit interesting properties including high mobility, and unusual resistivity be…
Interplay between breathing mode distortion and magnetic order in rare-earth nickelates NiO within DFT+
Alexander Hampel, Claude Ederer
We present a systematic density functional theory (DFT) plus Hubbard study of structural trends and the stability of different magnetically ordered states across the rare-earth…
